Another, not so important issue - The Insider has a battery backed clock on it. Where have they hidden the battery?! Am I really going blind?
If it is like the Spirit, its a big black "square" in the corner of the board (in the below picture, it is top left corner/opposite CPU). Inside that "block" is a coin style battery. To replace it, you will have to use a dremal to cut it open. Best bet is to get the 2 contacts instead that come from the battery and solder a new one one. There is a complete "step by Step" somewhere, but google is not being co-operative right now. it could even be in the photo's here.
EDIT: Yup in the gallery pages
